摘要: 本文采用J-116B胶黏剂和J-375胶黏剂,通过共固化的成型方式制备了胶接试样,并对胶接试样进行了湿热加速老化,测试了老化前后胶接试样的拉伸剪切性能,并分析了性能差异原因及界面破坏机理。结果表明:AC531树脂与J-375胶黏剂之间的界面相容性优于AC531树脂与J-116B胶黏剂之间的界面相容性,这是由于AC531树脂与J-375胶黏剂固化反应工艺窗口重合度更高,两者的表观活化能更加接近。

Abstract: In this paper, J-116B adhesive and J-375 adhesive were used to prepare adhesive samples by co-curing molding method, and the adhesive samples were subjected to wet heat accelerated aging. The tensile and shear properties of the samples before and after aging were tested, and the reasons for the difference in properties and the mechanism of interface failure were analyzed. The results show that the interfacial compatibility between AC531 resin and J-375 adhesive is better than that between AC531 resin and J-116B adhesive. This is because the AC531 resin and the J-375 adhesive have a higher degree of overlap in the curing reaction process window, and the apparent activation energies of the two are closer.

Key words: interface compatibility, co-curing, damp heat aging, reaction thermodynamics, composites
